Answer:
5.7 meters
Step-by-step explanation:
Image a rectangle being cut diagonally in half, that would lead to two triangles. We can use the pythagorean theorem to find the missing side. 
7 is the hypotenuse and 4 is the side length
4^2+x^2=7^2
16+x^2=49
sqrx=sqr(49-16)
x=sqr33
x=5.74
Rounded to the nearest tenth is 5.7
 
        
             
        
        
        
Answer: You would put the 35° and the 4x+7° equal to each other.
Step-by-step explanation:
     1. 4x+7=35  
     2. 4x+7=35   -> Subtract 7 from the positive 7 and the 35
            -7     -7
     3. 4x=28       -> Divide 4x and 28
     4. x=7
 
        
             
        
        
        
Answer:
c. Put them alined straight and centered X to B to W and now you get the answer so it's C. 
 
        
             
        
        
        
For this case, what we must do is solve the following system of equations:
 tan (50) = h / x
 tan (40) = h / (x + 50)
 Solving the system we have:
 (x + 50) * tan (40) = h
 (x) * tan (50) = h
 Matching:
 (x + 50) * tan (40) = (x) * tan (50)
 Rewriting:
 x (tan (50) - tan (40)) = 50 * tan (40)
 x = 50 * tan (40) / (tan (50) - tan (40))
 x = 118.9692621
 Substituting:
 h = (x) * tan (50)
 h = (118.9692621) * tan (50)
 h = 141.7820455
 Answer:
 The height of the building is:
 h = 141.7820455 ft
        
                    
             
        
        
        
Answer:
11.25
Step-by-step explanation:
4.5 / 2 = 2.25 cups/ cup rice
2.25 x 2 cups of rice = 4.5 cups of water.
5 x 2.25 = 11.25
